【Comment】

This is the first Rolex Master Rolex watch manufactured in 1954. Its most prominent features, in addition to the use of the “Benz needle” and the second hand with a large triangular tip instructions, but also the use of special rubber made bezel. The purpose of Rolex’s initial selection of this material was to be strong and durable, and then it would not affect the pilot’s line of sight because of reflections. Starting in 1956, Rolex began to use metal to make bezels (such as the 1675 gold second-hand bezel), and later began to use ceramic materials.
